1'0 aZZ whom it may concern:

Be it knownthatLPnrnron H. KANE, a citizen of the United States,residing at Oil City, in the county of Venango and State ofPennsylvania, have invented certain new and useful Improvements in CarLoading and Unloading Devices; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable oth-' ers skilled in the art to which it appertains to make anduse the same.

The nature, scope, and purpose of this in vention willfully appear fromthe following description and claims.

The functions of the device are such that a railroad-car can be raisedor lowervd, turned so as to face in any desired direction, tipped sothat, if it is an open car, its contents will be dumped or spilled fromthe car, and, lastly, to weigh-the contents of the car.

The'objects or purposes of thus handling a car, are:

First. That the car may belowered so as to i receive massive pieces offreight without lifting the same up to the car. This use of the devicewill be specially desirable at points where cars or locomotives or largemachinery of any kind are to be loaded. 1 Where this function alone isto be wanted, the device need not necessarily be provided with means forturning or tipping the car.

Second. That the car may be raised up and, if wanted, turned to face atan angle to the track, and tipped so as to dump its contents. This useof the device will generally be for unloading cars freighted with coalor iron ore,

and particularly where the contents are to be transferred directly intoa ship. When thus employed the device will receive a loaded car from themain track in the same manner as a common turn-table. It will turn thecar so as to face in the direction its contents are to be dumped. Itwill then raise the car, if necessary, to a proper height, and then tipthe car so its contents will be dumped out. The device maybe made so asto tip the car, and, not-so as to turn it, or to turn and tip and nothoist it, orit may be made, as here shown, so as to perform all thesefunctions. This will depend on the requirements, of course.

Third. That the weight of the contents of the car may be determined. a

The device is illustrated in theaccompany ing drawings, as follows:

Figure l is a side elevation. Fig. 2 is a like ing principal parts: Abase, A, with a'central pivot, A, and a fixed concentrically-arrangedgear, B, a superstructure which consists ofa platform, 0, mountedpivotally on the base A A, and an upright frame-work, 0 0 twolifting-jacks,.E E E E, and a car-receiving platform, D, mounted ontrunnions D, which are journaled on the jack-pistons E E.

The operating mechanism consists of a steam-engine or other motor, H,mounted on the platform 0; a main shaft, G, operated by said engine; apump, F, for operating the hy drostatic lifting-jacks, which is operatedfrom said main shaft G; a pinion, B, mounted on the said platform 0 andgearing with the large concentricallyarranged gear B on the base, andoperated from said main shaft G by the beveled gears B B, for thepurpose of turning the superstructure pivotally on the base;- and,finally, segment-gears D D, connected with the car-platform D, andarranged concentrically with itstrunnions D and operated from worm-gearsD which are operated from the main shaft, G by the intermediategearings, I I I I 1 I I and D*, and the shafts I 1 which latter devicesare employed for tipping the ca'r-platform soas to dump the con-' tentsof the car.

The device for weighing the car and contents consists of an ordinarypressure-gage, K, connected with the chamber of one of the hydrostaticjacks by a pipe, k. By this device the weight of the whole masssustained by the jacks can be noted both before andafter the car isloaded or unloaded, as the case 5 The device, as shown, consists of thefollowmay be, and the difference between the two I weights shown will bethe weight of the contents of the car.

. above described. 4

The construction as shown in the drawings is as follows: The base A maybe mounted-on.

masonry,or on a track which will be on a substantial foundation, Forinstance, if the device is used on a dock for loading coal, &c.,ontoships' itmay be mounted on'a broad, firm track, so it can be movedfrom point to point along the dock, so as to be used at the termini of a'series of tracks. The pivotblock A and the large gear 13 will be firmlysecured to the base A Friction-rollers b are provided for supporting theouter edge of the platform 0. The frame-work C Chis firmly secured tothe platform 0, and where desired it may be further sustained by guys 0c c,

which connect with wheel, Gfl whieh ispivoted or'swiveled to thecrown-block G of the frame. This swivel allows the frame to, re volvewhile the guys stand still. The uprights c of the frame serve as guidesfor the trunnion-boxes of the car-platform, which set on the pistons E Eof the hydrostatic jacks E E, which are arranged within openings in theparts 0 of theframe-work. The hydrostatic jacks are both connectedwiththe pump F by pipes ff, and thus both jacks are affected ex actly alikeand simultaneously.

f 3 represents the supply-pipeleading to the pump, and f the waste-pipe,by opening .which the jacks are relieved of fluid and lowered. The pumpvE is operated by an eccentric, F, on the shaft G. The eccentrie F isprovided with a clutch for throwing it into action. I have shown this asa ratchet-clutch, the shifting part of which is on the pinion B which ismade to shift and be put in gear with either the eccentric F or the gearB, on the stem of the gear B, by which the superstructure is revolved.This double service of the part B is practical, because it will not bedesirable to be working the .pump during the operation of turning thesuperstructure on its pivot.

'The mechanism for tipping the car consists of the segment gears D Dwhich are arranged concentrically with the trunnions D D of thecar-platform D and the worms D D and their operating-gears. The wormsare mounted in brackets L on a frame, L, which is hung by straps L L,which pass up over the trunnion-boxes. The frame L is provided on eachside with guide-heads Z, which embrace splines Z on the inside of thejack -barrels E. The frame L is thus supported in a horizontal position,and so that it moves up and down with the car-platform. On this frameissupported the following gearing for actuatingthe worms D D namely: theshafts I and I and the gears 1 1, 1 I and Di. The shaft 1* extendsthrough a slot in the frame-piece O on the side toward the shaft G, andis journaledin an angle-bracket, i, which supports the sliding beveledpinion I on the upright shaft J, which is provided with a spline, j. TheshaftJ is revplved from the main shaft G by the gears I I. When thecar-platform is moved vertically,- the gear I is moved vertically alongthe shaft J by the bracket 2', and is thus always kept in gear with thepinion I on the shaft 1*. By this means the car-platform canbe tippedwhen at any elevation desired. The main shaft G passes the upright shaftJ by a counter-"shaft,

G, and gears g g, as the construction is illustrated. The car isreceived on the tracks d on the platform D, and secured thereonin anymanner desirable, (I show it. secured by chains,) so it will be held 011theplatform as it tips.

The endboards of the car may be made re; h movable or be hinged, so astolet down or swing up, or they may be fixed and immov: able, In thelatter case of course all the, contents of the car willnot dump out, buta small part will be kept back by the end-board, and

will have to be shoy eled out. When the endboards are fixed, it will bewell to provide a sheet-iron hood to go overthe end of the car and forma spout or covered chute.

c I do not intend to be limited to the use of hydrostatic jacks, for anyof the well-known forms of jacks can be used in the connection hereshownby providing proper operating mechanism; but I consider the hydrostaticjack the bestfor the place.
